Lido, a leading Ethereum liquid staking protocol, has put forward a proposal to allow lenders to use ezETH as collateral on Aave's Lido market and Sky (formerly MakerDAO) to borrow wstETH and USDC. The supply cap would be set at 15,000 ezETH. If approved, the voting period would last five days. This move would increase the utility of ezETH and provide more options for lenders and borrowers in the DeFi ecosystem.
